The Mopar TPS shown is for the 4.0, it doesn't state that it can be used for the 4.7 as well. Don't know what the difference between the two is.You could try www.justforjeeps.com as well, they only have OEM parts. Check out their thread in the vendors section, they will give a discount.Also don't know what you mean with a connector piece. There should be a connector at the end of the wire loom, which attaches to the TPS.
